The image is constructed, maintained and updated within the Unix server’s frame buffer, and transmitted across the TCP/IP network. Note: this protocol is public and the associated software is free. For more information please see http://www.uk.research.att.com/vnc. VNC protocol information: - Server side: the VNC server daemon (Xvnc) is required. This software is an X server with embedded VNC. - Client side (called VNC viewer): the AX3000 must support VNC. - VNC protocol key points: display update requests are sent by the viewer. An update request can be incremental (the part of the display that changed is transmitted) or total (the complete display is updated). 2 Installing and Using the Axel-VNCviewer - 2 - SETTING UP THE PLATINE Installing and Using the Axel-VNCviewer 3 2.1 - SETTING UP A VNC SESSION This chapter deals only with the VNC session set-up. We assume that the other set-up parameters (such as AX3000 IP address, hosts, routers, etc.) have been already set. For more information please read AX3000 TCP/IP - User's Manual. To set-up a VNC session, enter the AX3000 Set-Up (<Ctrl><Alt><Esc>) select [Configuration]→[Terminal]→[Session X] (where X is the session number). The following dialog box is displayed: Set the following parameters: - Protocol: vnc - Host: the hostname on which the Xvnc daemon is run - TCP Port: numeric value associated with the DISPLAY environment (see Chapter 3): 5901 : DISPLAY = 1 5902 : DISPLAY = 2 …. - Auto Connection: yes or no, to automatically connect this session on power up. 4 Installing and Using the Axel-VNCviewer - Auto Reconnection: yes or no, to automatically connect this session on re-connection. - General Parameters: press <Space> to display the following box: These parameters are: - Resolution: the default resolution of a VNC session is 800x600. Press <Space> to change to 1024x768. Note: to check if the 1024x768 resolution is available refer to Chapter 6.4. - Shared Session and Keyboard and Mouse Ignored: these parameters allow several VNC terminals to share the same graphical display. For more information, refer to Chapter 6.2. - Local Mouse Cursor: if 'yes', the local mouse cursor location is indicated by a little square pointer (2x2 pixels). This could be useful when the local mouse cursor location is different from the VNC cursor location (for example when the Unix/Linux box or the network are overloaded). - Emulate a 3-button Mouse: if 'yes', the mouse middle button is emulated by clicking both left and right buttons. - Mouse Accelerator: if 'yes', the AX3000 speeds up the mouse cursor. Note: after exiting set-up, we advise a power-cycle of the AX3000. Installing and Using the Axel-VNCviewer 5 2.2 - SETTING UP THE MOUSE The VNC Platine Terminal controls either PS/2 mouse or a serial 2-button mouse. 2.2.1 - PS/2 Mouse The PS/2 mouse is automatically enabled when a VNC session is set. In event of problem, enter the AX3000 Set-Up (<Ctrl><Alt><Esc>) and select the [Configuration]→[Terminal]→[General] menu. Within the displayed dialog box, set the "Mouse" parameter to "PS2". 2.2.2 - Serial 2-button Mouse Attach this mouse to the AUX2 port (if needed, use
